BACKGROUND: Hepatitis C virus (HCV) infection is a common susceptibility factor for porphyria cutanea tarda (PCT). Experience on HCV treatment in patients with PCT is limited. Recently, HCV treatment has improved with direct-acting antivirals (DAA). We review our experience on HCV treatment in patients with PCT with older and newer regimens. MATERIALS AND METHODS: A retrospective chart review was conducted. HCV treatment was attempted 22 times in 13 patients with PCT (5 attempts in 1, 2 in 5 and 1 in the other 7 patients)...

Histiocytic necrotizing lymphadenitis or Kikuchi-Fujimoto disease (KFD) is characterized by its rare occurrence. Mostly prevalent among Asian women, KFD manifests with lymphadenopathy-affecting mostly cervical and rarely generalized or retroperitoneal regions-in addition to fever. It is a self-limited disease that resolves within 1-4 months, responding remarkably to glucocorticosteroids or hydroxychloroquine. However, some rare cases prove to be unresponsive to the previously mentioned therapies. Here is a description of a case of KFD affecting a 67-year-old Syrian woman with a history of hypothyroidism due to iodine-deficiency...

Childhood-onset systemic lupus erythematosus (cSLE) is a rare, multisystem and potentially life-threatening autoimmune disorder with significant associated morbidity. Evidence-based guidelines are sparse and management is often based on clinical expertise. SHARE (Single Hub and Access point for paediatric Rheumatology in Europe) was launched to optimise and disseminate management regimens for children and young adults with rheumatic diseases like cSLE. Here, we provide evidence-based recommendations for diagnosis and treatment of cSLE...

A fast UHPLC-UV method was developed for the simultaneous analysis of Hydroxychloroquine, Minocycline and Doxycycline drugs from 100μL of human serum samples. Serum samples were extracted by liquid-liquid extraction and injected into a phenyl hexyl reverse phase column. Compounds were separated using a mobile phase linear gradient and monitored by UV detection at 343nm. Chloroquine and Oxytetracycline were used as internal standards. Lower and upper limits of quantifications, as well as the other levels of calibration, were validated with acceptable accuracy (<15% deviation) and precision (<15% coefficient of variation) according to the European Medicines Agency guidelines...

REVIEW
Cynthia I Chude, Ravi K Amaravadi
Eukaryotes use autophagy as a mechanism for maintaining cellular homeostasis by degrading and recycling organelles and proteins. This process assists in the proliferation and survival of advanced cancers. There is mounting preclinical evidence that targeting autophagy can enhance the efficacy of many cancer therapies. Hydroxychloroquine (HCQ) is the only clinically-approved autophagy inhibitor, and this systematic review focuses on HCQ use in cancer clinical trials. Preclinical trials have shown that HCQ alone and in combination therapy leads to enhancement of tumor shrinkage...

BACKGROUND: Chikungunya virus infection (CHIKV) is caused by a mosquito-borne alphavirus. CHIKV causes high fever and painful rheumatic disorders that may persist for years. Because little is known about interventions for treating CHIKV-related illness, we conducted a systematic review. METHODS: We used Cochrane methods. We searched PubMed, EMBASE, Cochrane Library, LILACS and other sources from the earliest records to March 2016. We had no language restrictions...

Ackerman's Syndrome or Intersticial Granulomatous Dermatitis with Arthritis has been an issue of increasing number of reports in the last decade which had focused its heterogeneous cutaneous and rheumatologic expression besides the initial manifestations reported by Ackerman and his group. Granulomatosis anterior uveitis has not been previously described. Some patients are reported to have positive autoantibodies but association with anticentromere antibodies has not been previously described as well, to our knowledge...

It is currently recommended that hydroxychloroquine (HCQ) be maintained during pregnancy in patients with systemic lupus erythematosus. Recent data suggest that this Toll-like receptor inhibitor may also reduce the recurrence rate of anti-SSA/Ro associated congenital heart block (CHB). This case report describes a unique situation in which a CHB-afflicted, HCQ-exposed pregnancy was electively terminated. The heart did not reveal any characteristic features of cardiotoxicity, providing further evidence supporting the safety of foetal exposure to HCQ...

A 44-year-old woman with seronegative polyarthritis presented with a 2-year history of a solitary, bluish-red, oedematous, nonscaly, annular and partially reticulated macule on her right thigh. Histopathological findings revealed perivascular and periadnexal lymphocytic infiltrate in the dermis. Alcian blue and colloidal iron stains highlighted mucinous deposit in the upper and mid dermis. Direct immunofluorescence showed a linear deposit of IgG and C3 along the basement membrane zone. Antinuclear antibody was positive at a titre of 1 : 80, with homogenous and speckled patterns...

Toll-like receptor 7 (TLR7) is associated with the pathophysiology of systemic lupus erythematosus and Sjögren syndrome, well-known diseases accompanying interstitial cystitis (IC). We studied TLR7 expression in the bladder of patients with Hunner-type IC (HIC) and its functional roles in bladder inflammation and nociception using mice. Bladder biopsy specimens were obtained from patients with HIC. Specimens from the noncancerous portion of the bladder of patients with bladder cancer served as controls. The specimens were examined by immunohistochemistry and real-time polymerase chain reaction of TLR7...

BACKGROUND: Lichen planopilaris is an inflammatory cicatricial alopecia, and its management is a challenge for dermatologists. We aimed to compare the efficacy of methotrexate and hydroxychloroquine on refractory lichen planopilaris. METHODS: In a randomized clinical trial, 29 patients were randomly allocated to receive either 15 mg methotrexate/week or 200 mg hydroxychloroquine twice a day for 6 months. Side effects, symptoms/signs, and laboratory tests were assessed periodically...

Macrocheilia is a challenging problem with a variety of underlying causes that are both local and systemic, and granulomatous causes underlie the majority of cases. In this study, we report on a 31-year old man who presented with a chronic lower lip enlargement and a nodular submental erythematous lesion. He was otherwise clinically healthy. Laboratory test results were within the normal limit except for a positive anti-double stranded DNA test result. A diagnosis of cutaneous lupus erythematosus was made on the basis of histopathology and direct immunofluorescence...

We recently showed that patients with primary Sjögren syndrome (pSS) have significantly higher bone mineral density (BMD) compared to healthy controls. The majority of those patients (69%) was using hydroxychloroquine (HCQ), which may have favorable effects on BMD. The aim of the study was to evaluate whether HCQ modulates osteoclast function. Osteoclasts were cultured from PBMC-sorted monocytes for 14 days and treated with different HCQ doses (control, 1 and 5 µg/ml). TRAP staining and resorption assays were performed to evaluate osteoclast differentiation and activity, respectively...

OBJECTIVE: Some sources urge caution when prescribing hydroxychloroquine (HCQ) to patients with glucose-6-phosphate dehydrogenase (G6PD) deficiency, presumably due to a risk of hemolytic anemia. There is limited published data, however, to support this risk. Additionally, not all patients with G6PD deficiency are at similar risk for hemolysis, and people with the African variant are at particularly low risk. Through a retrospective chart review, we aimed to quantify the frequency of G6PD deficient patients with hemolysis attributed to HCQ...

Interstitial lung disease occurs in up to 25% of patients with Sjögren's syndrome and 2% - 8 % of patients with systemic lupus erythematosus. Corticosteroid therapy remains the main treatment for systemic lupus erythematosus. However, it can be associated with several neuropsychiatric disorders especially with prednisolone at a dose of more than 40 mg/day. We present the case of a 51-year-old patient with systemic lupus erythematosus and secondary Sjögren's syndrome with severe pulmonary involvement four years after the diagnosis...
